Compact box with 4 MIDI INs + 4 MIDI OUTs. It's connected to the PS/2 port of the keyboard via the ET parallel port (which isn't great)
SMTPE sync (never used)

USE

I had no issues installing it on a duron 700 + Abit KT7 system running W98SE and the original driver
"Transparent" use with Cubase. Every MIDI input/output is displayed with the desired name.

OVERALL OPINION

Having tested a Midi USB interface before (the emagic MT4), which crashed Cubase regularly, I've had no issues after upgrading to the MT4140.
Apart from the connection via the keyboard port (I would've preferred a separate PSU), it's all good!
